Then he said to all,
"If anyone wishes to come after me, he must deny himself
and take up his cross daily and follow me.
For whoever wishes to save his life will lose it,
but whoever loses his life for my sake will save it.
What profit is there for one to gain the whole world
yet lose or forfeit himself?"
What in the world does that passage have to do with Lent? What you quoted ought to be true of the life of the believer every day. How do you translate that into a 40 day season (for some of obligation) preceding Easter? That is absurd! You are bordering on eisegesis, and that is unacceptable.
